To all whom t may' concern: y

Be. it known that I, CHARLES PHILO MosHER, a citizen of the UnitedStates, and

a resident of Groton, county of Tompkins,

' and State of New York, have invented cer-y` tain'new and useful yvlVritmg Machines,

Improvements in vTypeof which the following is a full, clear, and exactdescription.

This invention relates ,more particularly to the ribbon mechanism offoldable 'Visible or front-strike typewriting machines in which the keysof the keyboard may be brought into close relation to the platen to makethe machine compact when not in use, andl is a division of myapplication Serial No. 56,242, filed October 16th, 1915.

One of the principal objects of the invention is to provide atypewriting machine in which a universal or standard keyboard may beemployed and in which the ribbon mechanism may be operated by the keysof /the keyboard and the entire keyboard and key action folded withrespect to the platen and l keyboard having individual keys foroperating individual type and whereinpthe pivotal part of the foldablesupport may serve as a connecting means between the keys and the ribbonmechanism for the platen carriage in order that no break ordisconnection is necessary whether the machine is in a folded positionor in an'unfolded position.

A further object of the invention is to provide a simple and efficientmechanism. for vibrating a ribbon to cover and uncover the printingpoint and for imparting a step-bystep lengthwise movement to the ribbon.

A still further object of the invention is efficient connecting meansbetween the ribbon mechanismvand the keys of the keyboard ofa foldabletypewriter. y

A still further object" of the invention is to provide the ribbon atypewriting machine in which. mechanism and the parts operaty ing ythesame are of simple construction and may bereadily made and assembled.

.lVith these and other objects in view, the invention will behereinafter more particularly described, with reference to theaccompanying drawings, which form a part of this application, and willthen be pointed out in the claims at the end of thedescription.

In the drawings, Figure 1 is alongitudinal section of one form ofmachine embody.v

Fig. 6 is a vertical sectionytaken on t'e line 'VI-VI of Fig. 2 of apart of the ribribbon lengthwise transversely of the n1achine. i

l While the invention shown as applied to a typewriter in which aninclosing case is employed, it will be understood that the foldingprinciple between the key-operated levers and the ribbon mechanism maybe embodied in a machine in which an ordinary o'r any preferred rform offrame may be employed or a frame independent of such case, and. thatsaid foldable principle as .well as the construction of the ribben viraloperating means therefor may be employed in typewriters of variousconstructions.

The casing has a main member 11 and a top member or cover 12 which 1shlnged at 13 to said main member 11.. At the forward lower edge of themain member 11 is a foldable member 14 which is pivoted or hinged at 15to said main member 1l so that said member 14 may be folded upwardly andwhen so folded and the cover 12 thereon moved over and forward as shownin Fig. 3, a substantially uniform and regular inclosing case isprovided. This member 14 may be held in its open position by means ofstays 16 or any other suitable means, and said stays may be slotted asat 17 to engage headed pins or studs 18. The stays are normally forcedin one direction by springs 19 and the slots 17 are curved orso arrangedthat in one position the stays will act as a lock, and when forcedagainst the springs 19 the case member 14 may be moved to its foldedposition. I

A foldable support or member 20 is pivotally held to atransverselyextending rod 21 which is supported in the sides of the main casingmember 11 or in sleeves which serve as the direct bearing for thesupport 20 and at its forward end said folda'ble support 2O may beconnected by links 22 to the member 14 so that the member or mipport 20may be folded with the member 14 of the case. The support 20 has sides23 which may be connected by a transverse bar 24 and mounted in said.support 20 is a segment 25. r1` ,fpe-bars 26 are pivoted to the segmentin any suitable way, as to a rod 27, and said type-bars are adapted tocarry a'plurality of type and be supported at their outer ends on acushion 28, the latter being held to a cushion supporting' frame 29extending out wardly from and supported by the segment. IThe type-barsare each normally forced in one direction by springs 30and are eachconnected by a link 31 to one arm of a bellcrank lever 32. Eachbell-crank lever is pivotally held to a rod or support 33. Y There arefour rods each being adaptedto support a plurality of the levers 32. Thebellcrank levers 32 each have one arm, as 34, provided with a cam edge34a which is adapted to engage a cam edge 35 of key-operated levers 36.These key-operated levers 36 are supported in groups or banks upon rodsor supports A37 which are horizontally arranged in the normal operativeposition of the machine under the rods 33 and correspond in number tosaid rods 33. As each key is depressed the cam edge 35 will operate @Uits coperating bell-crank lever and through a link 31 will move the typebar upwardly and rearward for printing purposes, and by reason of thearrangement in groups or banks a substantially uniform touch isobtained.

Laeaaoe ranged in the raceways to adapt the bed and carriage to traveleasily transversely of the machine. The carriage may have end plates '44in which is mounted to rotate the usual platen or roll 45. The carriagemay have the usual paper apron 46 'and the usual linger knobs 47 forrotating the platen. and

may also be provided with the usual or any preferred form ofline-spacing means, paper fingers and other attachments usually em-`ployed in typewriting-machines, but as such features form no part of thepresent invention it is thought unnecessary to describe or show them indetail.

To vibrate the ribbon and to move the same lengthwise of the platen in afoldable typewriting machine it is necessary that provision be madewhereby the folding principle involved will permit the operation of suchribbon mechanism by the depression of the keys during the printingoperation. As onev means, I provide a universal bar 48 which issuspended by arms 49, the latter being pivotally held at 50 onthetype-bar segment 25, there being any suitable number of arms 49 or othersupports for the bar 48.

The universal bar 48 is adapted to be engaged by the rear cam edge 51 ofthe typebars 26. The purpose of the cam edge 51 of the type-bars is tostart the universal bary gradually during the upward and rearwardmovement of the bars and to give the universal bar an acceleratedmovement without altering the uniform characterof the touch of the keysand in order that no sudden jar on the keys may be apparent to theoperator when the type-bars start to actuate said universal bar. At therear of the universal bar are upwardly extending arms 52. These armsrest idly at their upper ends against the rear surface of the universalvbar 48, and at their lower ends are held to a transversely extending rod53, the latter being pivotally held at its endsin the sides of thesupport 20. Arms 54 project forwardly from the rod 53 and said arms`have their forward ends slotted to engage pins 55 carried by the innerends of arms 56. The arms 56 are held to the transyersely extendingpivot rod 21 and serve,

when the universal bar moves the arms 52,

' which one end of the rod 2 1 passes, said cam member 58 being normallyforced inwardly by means of a spring 61. The slid'- ing canrmember 58 isprovided withan annular Igroove which is engaged by the forked end 62 ofa llever` 63.

pivoted at 64 to a lug on one of the sides of the main casing member 11and has its upper arm 65 extending inwardly and pro- Y vided with aslotted or forked end 66 which described, the said rod is adapted toengage a pin 67 extending outward from a rod 68, so that on eachmovement of the lever 63 as will be presently 68 by means of the pin 67will be rocked.- on its pivot pins or screws located 'at't "e endsthereof.

The rod or shait'68 serves as the direct operating or connecting meansfor the vibrating mechanism for the ribbon to move the latter to coverand uncover the printing point, and as ameans whereb may be operated togive the rlbbon a stepby-step movement lengthwise in the direction ofmovement of the platen, the ribbon mechanism if desired beingconstructed to adapt the ribbon to have a plurality of fields or zonesof different colors, or to remain inactive forstenciling purposes. Asshown, the rod or shaft 68 has an arm 69 projecting outward therefromwhich is connected to one end of a link 70. The link 70 is connected to.an outwardly extending arm 71 which is pivoted at 72 to a bracket 7 thelatter having downwardly extending arms secured to the plate 41 forminga part of the carriagetrack. The arm 7l forms a part of a ribbonvibrator and at a portion thereofl may have outwardly extending spacedlips or parts 74 forming a type guide or aliner. A plate 75 may besecured to or formed integral with the arm 71 and this plate forms aribbon holder through which the ribbon'76 is threaded. The plate orholder 75 has openings 77 and is provided with spaced parts 78 formingsuitable guidesl for the ribbon on opposite sides of the printing point,said parts 78 being spaced apart -far enoughto permit the type to printagainst the platen. As the rod 68 is rotated oroscillatedby themechanism already described, the arm 69 will move the link 70 andthroughthe latter vibrate the ribbon old one.

The lever 63 is substantially bell-crank shaped and is mechanism holder75 and aliner 74, thereby causing the ribbony to cover and uncover thepoint as each key is operated,

The ribbon extends beyond the sides of the ribbon vibrator and-may beguided in the ends 79 of the brackets80, said ends having slots 81 forthe ribbon to pass through. The'ends ofthe ribbon are passed aboutspools 82 and 82. These spools are mounted to rotate on a fixed part ofthe printingy casing and are adapted .to be readilyremoved to permit-anew ribbon to replace an provided with a ratchet, rg toothed portion ormember 83 formed ont `:he spool or separate therefrom as preferred, andadapted to engage the or dog 84. Each pawl 84 is pivotally held at oneend to an arm '85, the latter being held to the rod or shaft 68, aspring 86v ednormally to force the pawl to' an en-` gaging position. Thearms 85 are adapted to slide along the rod 68 and said arms for bothspools are connected by. a transversely extending bar or element 87havingv one or more substantially V-shaped projecting portions 88adapted to engage notches 89 in said rod 68. The arms 85 are sopositioned that only one pawl is engaged with the teeth of the toothedmember of one of the Aspools at a time so that by shifting thebar 87lengthwise of the` rod or shaft 68 one pawl' is disengaged from itscoperating spool toothed side of the machine with a step-by-stepmovement. I i."he rod-A 68 is thus operated through the lever 63 and itsconnection with The' ribbon spools may each be teeth of each member isapaw-ll thus the ribvso being arranged on each of said arms adaptthe keyaction as previously described ,an-d ,v

by the rocking movement of said rod or shaft 68 the ribbon is movedlengthwise and also vibrated to cover or uncover the ing point as shownin full lines in'Fig. 1.

Any suitable means may 'employed as an escapement mechanism forletter-spacing the carriage. As shown the carriage has .a rack 90secured to the base 89, and engaging this rack is a pinion 91, saidcarriage being attached to a iiexible connection 92 which passes about aspring drum 93 tendingnormally to force the carriage transversely of themachine. The pinion 91 is held to a ratchet wheel 93, and the teeth ofAthis ratchet wheel are engaged by a'pawl 94 carried by a toothed wheel95, said pawl permitting the carriage to be moved freely in onedirection.

The toothed wheel 95 is engaged by the usual loose or'limber dog 96 anda-xed dog 97 said dogs being held to the rod 68 so that when said rod isoperated by the depression of any of the key-operated levers 86, aspreviously described, the dogs will be moved to permit the toothed wheel95 to escape and print-` ployed inv which thereby permit rthe carriageto move a letter splicevateach depression of a key-operated l 56 in" theusual way, it beingunderstooil'ffthat the escapement, may be operatedthrough a source independent ot' the means employed r operating theribbon vibratory ani'blrif hw se feeding means.
